Our story
About Drain Doctor Plumbing & Rooter
Drain Doctor Plumbing & Rooter is a family-owned and operated business that has been providing high-quality plumbing services and repairs to the Los Angeles and San Bernardino Counties since 1996. Our professional plumbing company can quickly and accurately diagnose any work that needs to be done, which allows us to give you prompt and fair estimates before any service has begun.
From drain cleaning and hydro jetting to sewer line repair, water heaters, and whole-home repiping, we keep the full job in-house whenever possible—our trucks, our cameras, our jetters—so you are not paying for middlemen or last-minute equipment rentals.
